Should anyone mix good Plugs with old Ones ? General answer is NO ! if you want to clean the old plugs use the old ones but Should Avoid Mixing the old and new just to save some money as it may cost you in the long term of the vehicle...Tip of the Day !
When removing old plugs use WD-40 or similar to spray on to the plugs and leave it for a few hours or over night this will help loosen the plugs and make removing them easier
if you have one you can use an automotive scan tool like a ODB2 Scanner , usually they have software to test the efficiency of the plugs and sometimes give you an answer if they need replacing or even which particular one
Symptoms of bad spark plugs can include but not limited to Symptoms of bad spark plugs can include, lack of acceleration,...hard to starts, Engine generally misfires, and not forgetting Rough idling.
Facts ! ...... iridium spark plugs can last up to 25% longer than comparable platinum spark plugs but tend to be more expensive , but defiantly worth it.
What 10mm socket? You work on rc nitro engine or what? That's way too small for normal cars, 14-18mm here it is 16mm. I had 17mm once, but 10mm no way, 8mm is glowplug on single cylinder two stroke rc cars
Some DIY Mechanics don't know that WD40 also helps avoid corrosion on spark plugs. It removes the dust and dirt from the spark plugs. It lubricates them. It improves the connectivity of the spark plugs, this is also the same for other engine parts like batteries, alternators, and distributors....Just thought i let DIYers know this as i like to help people
Always Note when spark plugs are changed in the service manual/book for future reference, and if the vehicle is to be sold as this adds value to the selling price
Great Vid as usual! But, I think this works great for a normal B200. I think with the Turbo version, there are a few things that are in the way. Perhaps a video on sparkplug removal on a B200 (W245) Turbo someday? Thanks!
You are right, we have made mistakes. However, in our new videos, we tried to correct all our mistakes and make the video as informative as possible. Thank you for watching us, it will only get better in the future. AUTODOC
Spark plugs have two primary functions , 1. To ignite the air/fuel mixture, transferring electrical energy through the wire to ignite the fuel in the main combustion chamber.
It is a good idea to use copper grease on the New Plugs Thread to ensure future replacement is easier to carry out ..stops any rust or ceasing of the plugs hence avoids snapping the plugs...this also applies to GLOW PLUGS too
I heard that too but maybe ceramic paste is better? Copper does "corode" and gets green with time and on an aloy engine block mixing copper under heat and pressure can lead to burn in... So no no on modern cars, clean threads and the right torque should do
Great Videos autodoc !!!! I like that they are all business and hands on, and the sub titles really help as well. I have a Turbo B200 so changing plugs on it are quite a bit more involved, it would be nice to see how the Pros do it, keep up the good work! Cheers.
Do allow the engine to Cool before any work is carried out preventing burns , this includes the entire Exhaust system, if you are working from underneath the car
Only if you don't get them out you can remove them while the engine is hot! The right tip should be: Only install and tighten sparkplugs on cold engine block! Never attempt to screw them in while the engine is hot!!!
Always remember that changing the spark plugs is a way of assuring top efficiency and performance and it helps produce less harmful emissions from the exhaust
Spark plugs do vary in the Quantity needed depending on the amount of cylinders the engine has can be 2, 4 , 6 ,8 ,10 and even 12 plugs needed, some engines can have 2 or more spark plugs per cylinder.
When removing old or highly used spark plugs you must ensure that EXCESS force is not used when cranking them As they can Snap , this will cause you a great deal of financial Pain, as the engine block need to be removed and the spark / glow plug needs to be drilled out manually
Misfiring of Spark Plugs can also be caused if the gap in the plus is too wide , so do check with the manufacturer for the correct GAP width. ..some times it is stated on the BOX of the Spark Plugs
I have personally found that when i remove all the spark plug in my car repairs and maintenance i sometimes shoot a small amount of engine oil into each spark plug hole, then i rotate MANUALLY by hand the engine to ensure that there are no other issues with the engine.
Could be fun on modern multi electrode versions :-) If you buy the right type and quality parts its definitely a no... Professional workshop got no time for that
Try to Avoid mis-diagnosing the problem of Spark Plugs as a ruptured of the intake manifold gasket can also lead to misfires... this is why i say use a SCANNER OBD2 to diagnose any problems before had.
The electrical energy is transmitted through the spark plug, jumping the gap in the plugs firing end if the voltage supplied to the plug is high enough. 12V usually
@@terry.chootiyaa yes we did.. He's not right, the plug itself doesn't get supplied with 12V end of message. Even if the supply voltage of the whole circuit is 12V which he clearly not said
When to replace spark plugs ? this is mainly dependant on the make and model of the vehicle. do check with the manufacture of the vehicle first before any purchases
There are alternate types of spark plugs that can be used too ... these are Iridium and Platinum plugs that are chosen for their longevity mainly, the main difference is the material that the TIPs of the spark plug is made of ,normal ones are usually copper, whereas the other two have tips made out of platinum or iridium, that is the only main difference
Video does not show removal of various ducting required before these steps. Also, the ads for auto doc are highly annoying at the start, both audibly and visually masking the start of the process.
Performance Spark plugs will have upto 3 electrodes per plug and is more effective and better in providing a longer life span along with better fuel economy if you use the vehicle on a daily basis compared to a single electrode Spark Plug.
Iridium spark plugs give you even better gas mileage along with performance, reliability, and longevity than double-platinum plugs....worth considering when replacing plugs
I just cannot get over how manufacturers today give zero thought, absolutely no thought for anyone wanting to repair a car themselves. Changing sparkplugs Step 1, lift the car off the ground. Are you fucking kidding me. Great video by the way and thanks for doing these. On behalf of all home mechanics, we salute you and keep up the great work.
Hello, i have the exact same car, while driving i notice that it seems to struggle accelerating and engine seems to shake while on idle so i always go on neutral while in idle mode , do i need to change all 4 spark plugs? Would appreciate your reply, thanks
Thank you for your comment! Unfortunately, it is not possible to answer your question, there may be a lot of reasons, we advise you to contact the service for a complete diagnosis and identify the cause of the problem. Best Regards, Autodoc team
If you are Storing your car for a long term period it is a good idea to remove the Spark Plugs and replace them with a set of "ENGINE DESICCANT SPARK PLUGS" these will help prevent rust ,corrosion and Moisture from building up in the engine and will keep your engine in pristine condition......worth checking out !
certain manufacturers develop through R&D Advance Plugs for longer lifespan, Pay that Extra and buy the BEST it really is worth it i know from experiance
Spark plugs don't last forever you know ! they deposit buildup of soot and other engine waste over time, they also expand making it harder for the spark plug to make electrical contact ..Hence Causing misfiring !
From my experience in life i have learnt that a wet spark plug can be the result of the engine flooding. ... You can clean the spark plugs or you can just wait for them to dry out before attempting to start the engine ...this was usually always the case with Older model cars
? The older engine has a carburetor which is not set hop right that's what's the problem. W245 or B200 does not, if spark plug is wet the could is broken
For videos like this, definitely need better angles or even a diagram/manual to help better illustrate positions as I know the room in an engine bay can be tight

Just go by foot..what next? Reuse old oil? Oh god no! Spark plugs were cheap compared to the car the are fixed to or you got shafted by the supplier
Mate Uncle Nirodh, you are too good, I am amazed at you knowledge ...all the best ! 👍👏👏
Changing Spark Plugs also increases Fuel Efficiency ! saving you on long term fuel savings
Always carry and set aside the correct tools for the task ahead
When removing old plugs use WD-40 or similar to spray on to the plugs and leave it for a few hours or over night this will help loosen the plugs and make removing them easier
How? The thread should be sealed against combustion pressure which is high! Hot motor block while removing helps
if you have one you can use an automotive scan tool like a ODB2 Scanner , usually they have software to test the efficiency of the plugs and sometimes give you an answer if they need replacing or even which particular one
*Uncle you are the PRO ! man 👍*
The electrical spark ignites the gasoline/air mixture in the combustion chamber ...AMAZING isn't it !

Spark plugs have two primary functions , 1. To ignite the air/fuel mixture, transferring electrical energy through the wire to ignite the fuel in the main combustion chamber.
number 2 is to draw heat away from the combustion chamber
And the second one was forgotten by the spambot but added by graham wilson

dielectric grease my boy
It is helpful to make a note of the order or the sparkplug leads in order of 1 to 4 , how ever many your vehicle has as they fire in sequence

We are glad that you enjoyed our videos.
We wish you Merry Christmas and Happy New Year!
Ya it is definitely more involved
Yeah you have to remove everything
Try doing the starter motor too 😂
Do allow the engine to Cool before any work is carried out preventing burns , this includes the entire Exhaust system, if you are working from underneath the car
Only if you don't get them out you can remove them while the engine is hot!
The right tip should be: Only install and tighten sparkplugs on cold engine block! Never attempt to screw them in while the engine is hot!!!
Always remember that changing the spark plugs is a way of assuring top efficiency and performance and it helps produce less harmful emissions from the exhaust
? The please replace the air filter regularly also!
25nm for the plugs, perfect thanks guys that's just what I was wondering.
If you spark plugs it is stated on the package, dependent on material/thread type every time! Look at the box and the Nm is stated there
Do wear the Correct PPE protection before carrying out any work on the vehicle for safety
Which ppe? Glasses is enough for this job

Always Take photos of before the work area and compare after you finish ...this is a general rule.

Always Check the Spark Plug gap , as sometimes it may need adjusting... do be aware of that !

Professional workshop got no time for that
Try to Avoid mis-diagnosing the problem of Spark Plugs as a ruptured of the intake manifold gasket can also lead to misfires... this is why i say use a SCANNER OBD2 to diagnose any problems before had.
Do Remember that Spark Plugs are Different from GLOW Plugs found on Diesel Cars...they are not the same.. just make that clear !
Always Torque the Plugs to the correct Nm to prevent damaging or destroying the Thread of the Plugs..... This rule is the same for Glow Plugs too.
if you are a Sports Car enthusiast and own a performance car then you may know that Iridium spark plugs are perfect to use on high-performance engines

But it is Also worth noting that a obstructed fuel injectors will also cause a misfire so us a Scanner to reconfirm
Spark Plugs are NOT universal so do make sure you have the correct ones for the vehicle.
Thanks 🙏 thanks
I guess some of the DIY mechanics may not know this but Iridium and Platinum Spark plugs can last upto 100,000 miles before needing replacement

Always conduct some research on what types of Spark or Glow Plugs will best suit your car before you purchase some
Also some plugs include a coating or pad of precious metals to extend plug life
Try the turbo version
standard spark plug typically uses a nickel-alloy outer material fused to a copper core

A "Special" Tool called a "Feeler Gauge" is needed to gap your spark plugs properly
Add in the Turbo version and the headache will increase as there is less room and everything is completed under the car.
